Circuit breaker with unitary actuating shaft

An electric switch comprising:

• a dielectric housing including at least one housing section having side walls and an end wall;
• spaced stationary contact structures for each housing section extending through the side walls and into the housing interior;
• a dielectric, hollow actuating shaft within the housing with one end of the shaft being journally-mounted in an opening in the end wall and the shaft being rotatable between open and closed circuit positions;
• a movable contact structure for each housing section mounted within the shaft and including a pair of parallel conductors having end portions clampingly engaging corresponding stationary contact structures when the shaft is in the closed circuit position;
• rotatable driving means for turning the shaft between the open and closed circuit positions;
• the shaft having aperture means, and the conductor extending through the aperture means;
• and
• each parallel conductor being mounted within a channel comprising a base and opposite flanges, each flange having notch means for contact with the shaft for preventing longitudinal shifting of the conductor.
